I know you can "mix" milk from more than session but for how long i.e. can you keep filling the same tub for say 3 days?
Can you store BM in the fridge and then move to the freezer?
Yesterday I expressed a pile of milk down the sink as was engorged - would there be any point in keeping this as it was v watery foremilk?
Do you have to warm BM or can you feed it cold?
How long can you carry it around out of the fridge for e.g. if you were going out for the day?
What would be the best quantity to store in one container? I have no idea how much DD takes in a feed...
